From 9ff67e5e4c719556d57f136a6453f8e4798d85c0 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sun, 14 Jun 2009 06:29:07 -0400 Subject: Blackfin: unify u-boot linker scripts All the Blackfin linker scripts were duplicated across the board dirs with no difference save from the semi-often used ENV_IS_EMBEDDED option. So unify all of them in the lib_blackfin/ dir and for the few boards that need to embedded the environment directly, add a LDS_BOARD_TEXT define for them to customize via their board config file. This is much simpler than forcing them to duplicate the rest of the linker script.
